The capacitance of the diode varies inversely with the value of the source voltage and thereby produces an impedance which varies directly with this voltage for the h.f. signal and a triggering voltage is only produced at the gate of thyristor 1 for near zero values of the supply 10, 11. Unrectified A.C. may be used with back-to-back thyristors or a triac. The diode 3 is then included in a series, opposed pair.

Title: Improvements in and relating to the electro-hydraulic remote control of hydraulic multi-position valves

Abstract: 1292162 Controlling fluid-flow electrically ROBERT BOSCH GmbH 6 Nov 1969 [6 Nov 1968] 54371/69 Heading G1N In an arrangement for controlling the flow of pressure medium from a variable stroke pump 11 to a load or loads by electro-hydraulically remotely controlled multiposition valves 13, 14, 15 an error signal derived from the comparison in electrical control device 17 of a signal from generators 22, 23, 24, whose magnitude corresponds to the displacement of the respective control lever 18, 19, 21, with a signal from generator 49, whose magnitude is dependent upon the position of a respective control slide 31 of the valve, is applied to an electrohydraulic setting device on the valve to move the control slide 31 to balance the signals. The control device 17 is in operative connection with a second electrohydraulic setting device 12 arranged to control the pump stroke of the adjustable pump 11 in dependence upon the displacement of the control lever 18, 19, 21. In the neutral position of levers 18, 19, 21 solenoid valve 63 is open and the almost zero delivery from pump 11 flows through changeover valve 61 to return line 52. When any of the levers 18, 19, 21 are displaced an associated cam 25, 26, 27 operates common lever 28 to produce an appropriate signal from generator 29 which via control device 17 closes, solenoid 63 and hence valve 61 so as to build up control pressure in passage 59. At the same time the signal from 29 is compared with the signal from generator 69 on the pump 11 representative of pump stroke and if the lever 18 is moved to the left an error signal is applied from device 17 to open solenoid valve 57 to result in an increase of pump stroke until the signal from 69 balances that from 29. Simultaneously the error signal from device 17 to valve 13 opens solenoid valve 47 and control slide 31 moves to the right to connect the load chamber 32 to inlet chamber 34 and load chamber 33 to return chamber 36. When the signals from generators 49 and 22 balance solenoid valve 47 closes and the slide is locked in the final position. When the lever is moved back towards the neutral position solenoid valves 55 and 45 are opened to decrease the pump stroke and move the slide 31 back to its neutral position, and at the neutral position change-over valve 61 is again opened. The slide 31 can be moved to the left in a similar manner by moving control lever 18 to the left. All the solenoid valves open if the electrical system fails and return device 37 moves slide 31 to its neutral position. In the arrangement of Fig. 2 (not shown) a feed pump is included to supply the control pressure to the setting device and in the arrangement of Fig. 3 (not shown) the control pressure medium is conducted to return line 52 directly by way of the solenoid valves 55, 57 and the change-over valve is omitted.
